Age is counted the way official forms do: full calendar years first, then full months, then leftover days — so someone born 15 March 2000 is exactly 26 years, 4 months, 0 days on 15 July 2026.
The second field lets you calculate age at any moment — past or future. Check how old someone was on a historic date, or how old you'll be when you retire.
Born on 29 February? In non-leap years your next birthday is shown as 1 March — the day you legally turn a year older in most countries.
The calculation runs entirely in your browser. Your date of birth is never uploaded, stored or seen by anyone.
Alongside your age you get your Western star sign (based on the day and month) and your Chinese zodiac animal (based on the year) — handy for birthday cards and quizzes.
Need days between two dates, or a date 90 days from now? Use our Date Calculator — it counts calendar days, weekdays and can add or subtract any period.
